Abstract :
Modern
fundamental physics contains ideas just as revolutionary as those of Copernicus
or
extra dimensions
of space, or the possible existence of other Universes.
Testing these
concepts requires enormous energies, far higher than what is achievable by
the Large Hadron
Collider at CERN, and in fact, beyond any conceivable Earth-bound
experiments.
However, at the Big Bang, the Universe itself performed the ultimate experiment
and left clues
and evidence about what was behind the origin of the cosmos as we know it,
and how it is
evolving. And the biggest clue is the afterglow of the Big Bang itself.
In the past
decade we have been able to answer age-old questions accurately, such as
how old the
Universe is, what it contains, and its destiny. Along with these answers have
also
come many
exciting new questions. I will present an overview of current cosmological
constraints from
the cosmic microwave background and large galaxy surveys, and comment
on some of the
experimental and methodological innovations that are needed to realise the
promise of upcoming
surveys.
